JOHANNES THEODOR PEDERSN, OF WOODSIDE, NEW YORK, ASSIGNOR TO PEDERSN MANUFACTURING COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.

LUBRICATOR.

l'o all whom it may concern:

Be it known that I, JOHANNES THEoDoR IEDERSN, a citizen of the United States, residing at W'oodside, in the county of Queens and State of N ew York, have invented an In'iprovement in Lubricators, of which the following is a specification.

My invention relates to the class of oil feeding devices or lubricators especially adapted to supply lubricating oil to the machinery of motor vehicles, motor boats, etc., and the saine is an improvement upon the device shown and described in Letters Patent of the United States, granted to me July 24, 1906, #827,032, and particularly to the sight-feed devicesof such lubricators, with the object of providing for an adjustable feed-flow in relative proportion to the overtlow and vice versa, or in other Words, for a decrease in the overflow relatively with the increase in the feed-iiow and vice versa.

The essential feature of my present invention consists in the valve device forming part of the well-known sight-feed structure of my aforesaid patent and employed for regulating and controlling` the quantity of oil delivered to be forced to the machine to be lubricated. This valve device has a twopart 1nember,-of which one part is manually actuated and revoluble and the other part is non-revoluble but adapted for axial movement by its co-action with the first aforesaid part, and the parts of the sightfeed device employed in connection with this valve are so constructed that whatever position the valve may occupy, the same amount of oil is steadily owing through the sightfeed; either all for lubricating purposes or all to the over-flow or graded proportions to each, according to the position of the valve with reference to the extremes of its movements.

In connection with the essential feature of my invention I do not limit myself to the balance of the structure employed in connection therewith, as the same may be changed and the oil receptacle and means for supplying the same may be changed without departing from my invention; it being possible to employ the valve structure of the present invention with various other and substantially equivalent combinations of parts.

In the drawings, Figures l, 2 and 3 represent by vertical sections and partial elevations the devices of my invention with the Specification of Letters Patent.

valve in the closed and open positions and in an intermediate position. Fig. 4 is a partial vertical section and elevation similar to Fig. l, but at right angles to the position in which Fig. l is taken. Fig. 5 is a plan of the parts shown in Figs. l to 4 inclusive. Fig. 6 is a sectional'plan on the dotted line ac, cc, of Fig. l for instance. Fig. 7 is a sectional plan on the dotted line i y, of Fig. 1. Fig. S is an elevation of the upper member of the valve structure and Fig. 9 an elevation of the lower member of the valve structure; Figs. l to 4 inclusive showing the parts of the valve structure in their connected relation, and Fig. l0 is a sectional plan on the dotted line e, e, of Fig. l.

a represents a portion of the cover of a suitable oil receptacle, tank, or other vessel, or a bar holder or support and to which the sight-feed devices are preferably connected. These sight-feed devices preferably extend above the cover, but I do not limit my invention to connecting said feed-devices to part of the cover of the oil receptacle, as a may represent a platform suitably supported.

represents the cylindrical sections of glass forming part of the sight-feed, and c-in each of the figures-an annulus into which the lower end of the cylindrical sections Z) of glass are received; this annulus fitting within an aperture in the part a and being suitably secured thereto. An annulus d is provided fitting over and around the upper end of each cylindrical section b of the device, and I prefer to employ suitable packing rings or washers directly between the ends of the cylindrical sections of glass and the inner surfaces of the annuli c cl.

In the lower portion of the sight-feed devices, e represents a thimble at the center of which is a pipe c1. The central portion of the thimble is made funnel-shaped for the discharge of the oil into the pipe c1 and this thimble fits snugly within and may be secured to the annulus c in any desired manner. At the upper end of the sight-feed device there is another thimble f which also is of the same configuration and centrally perforated, there being by preference a central nozzle portion to this thimble. The upper part of this thimble is made as an interiorly threaded sleeve f1 and below this sleeve the thimble is exteriorly threaded so as to screw into the upper annulus CZ. A pipe g passes through the thimble e, through the sightfeed and up into and through the thimble f, the same being left open at its upper end.`

A pipe h. also passes vertically through the sight-feed. through the thimble e and into and .through the thimble with its upper end open and these two pipes are advantageously set diametrically opposite lto lone another.

A cap e' centrally apertured lscrews into the sleeve f1 of the thimble f to close the same and to serveas abearing for the upper member of the valve. The rupper -member of the Ivalve is composed of the stem f-and the flange .751. The lower part is *hollow orapertured and internally threadedtat 2. The upper part isalso aperturedand made tubularvand provided `with notches or lkerfs 3 to receive a screw driver or other implement by which the upper member of the valve is rotated to a Ygreater or less extent. The vlower member of the valve comprises the-exteriorly threaded stem Zland the conical head m, between -which there is a cylindrical portion m1 vin `which is secured 1a vpin el.

The upper-end of the pipe g or it may be the pipe /L is slotted to receive a projecting end of the pin e and the cylindrical portion m1 of the lower valve member is received within and movablethrough a central aperturefof the thimble (see particularly Fig. 4t); there being' .fa seat or ledge of this thimble f lupon which the lower surface of the flange 'fl of the :upper revoluble valve member bears; the cap z' screwed down -to place in the sleeve .f1 serving to keep -thc upper valve member in positionand -prevent axial movement longitudinally, but permits a revoluble movement on its axis.

The valve members shown in Figs. S and 9 are connected-by the screw stem Z and the internal thread 2 of `the upper member, and by virtue of the fact that vthe upper member 7.: is revoluble and the lower 1member can only'movelongitudinally, or in .the direction'of its axis, because of its pin el being ina slot at'the upper end of the pipe g,-it is evident that the revoluble movement of the upper valve Imember will by virtuefof the screw-threaded connection of the-two parts7 produce a longitudinal :movement of the lower member, forcing the conical head ofthe Vloweranember to its seat as in Fig. l, or withdiawing thesame partially from its seat as in Fig. 3. or wholly from its seatas in Fig. 2.

yBy reference to Figs. l .and i, `in which Athe conical head of-the valve is close to its seat, it will be apparent that there are passage-ways for the oil :at either side of the stem -Z between the opposite 'walls of the lthimble f and between the pipe y] and the :pipe L, so that in this position of the memvbers of the valve with the orifice of the thimble entirely closed, the oil will as forced, pass up the pipe g across through -the passage-way (Bland down the pipe lz..

Asthe ylower memberof the valve iselevated by the rotation of the upper member of the valve and the conical head m is raised from its seat in the thimble f, the upper surface of the vertical portion m1 ycomes closely vto the under surface of the flange u1, restricting the opening through which the oil passes from one pipe to the other,.and.at thesame time opening up the thimble apertureso that a certain proportion of the oil is vfree to pass down into the thimble f aroundthe conical head m and be discharged from the thimble f into the pipe el at the bottom of the sight-feed devices. rllhis position is represented in Fig. 3 where party of the oil is vforced up the pipe g and passed over into the pipe L and apart is delivered from the thimble f into the pipe c. lith the further rotation of the upper valve member, the lower valve member is raised to the limit of its position shown in Fig. 2,4m which the upper surface off-the cylindrical portion m1 comes into direct contact with theunder surface of the flange 1:1, entirely 'closing rthe opening G hereinbefore referred to and preventing any oil `passing Afrom the 2pipe g over into ythe pipe/abut compelling all the oil that comes up the pipe g to ,pass down into the conical portion ofthe thimble tg-around the conical head m-to be discharged from the thimble into the pipe c. AFrom the position of the 1parte shown in Fig. l7 all the oil that is forced up the pipe g .from the receptacle is by the pipe 7L returned to the receptacle and from -the position shown in Fig. 2, all the oilthat is forced up the pipe y from the receptacle, descends through the thimble j and pipe e :to be delivered for lubricating purposes, while. iu the rposition of the parts shown 1in Fig. 3, in which the lower member of the valve is atan intermedi ate point, a part ofthe-oil which .is forced up the pipe g is bythelp'ipe 7L returnedto the receptacle, and the other part descends through the conical vpart -of the vthimble f, around the conical head mV of the lower valve member and flows from the orifice ofthe thimble f into the pipe 1 to be directed to the parts to be lubricated. .lt will -ft-herefore be apparent vthat all of .the oil may be returned to the ,parts are so proportioned.and regulated by preference, that either one of the eXtreme `positions described., ou any one of the adjusted intermediate positions described, are capable of *.ta'klng care of all kthe oil that 1s forced up the pipe y] from the receptacle.

From the sectional plan Fig. 10, the .relative size of the seat or ledge 5 upon which the under surface of the flange 701 bears and the passageways G for oil around the stem Z across from one pipe to the other will be apparent, and it will also appear plain that when the cylindrical poi'tion ml of the lower valve member is raised to the flange 751, that the passageway G will be entirely closed off, the notch in the pipe g for the pin 4 then serving for the discharge of the oil from the pipe g into and away by the conical part of the upper thimble f.

Vhile I have shown and described the upper member of the valve as tubular at the lower end and interiorly threaded and the lower member of the valve as formed with a threaded stem, it is obvious and entirely within the scope of my invention to reverse these conditions and make. the upper member with a depending threaded stem and the lower member tubular and interiorly threaded as the. function and operation of the valve device would not be changed at all thereby.
